Is there any rule or regulation I should know about recreational or commercial shellfish harvesting?

 Before you head out to your favorite shellfishing spot, you need to check out whether the area is closed for harvesting. There are three types of closures: regulatory closures, temporary emergency closures, and special shellfish closures. Shellfish harvesting closures and limits are both available on-line.
